If you have an STI, you can infect other people, even if you have no symptoms. That’s why you should notify (anonymously) all sexual partners. They could also have the STI and inadvertently transmit it to other people. Sometimes with serious consequences. Discuss with the doctor who should be notified. You should usually notify sexual partners from the last six months. Sometimes you should notify people you had sex with one or more years ago. If you do not want to tell someone yourself that you have an STI, the municipal health service can notify sexual partners with your permission. If you yourself are notified about an STI, take it seriously. Have an STI test, even if you have no symptoms.
